I don't understand this code so I'm not really qualified to review it.  Thanks
for the heads up, though.  I'll keep an eye on the buildbots as this lands.

I also wonder if we need some assertAlmostEquals instead of assertEqauls. But
that shouldn't hold up this patch.

I would only switch to assertAlmostEquals, if we see a failure or flake that
requires it.
